Perfecting the Open Source RC Controller

Over the last few months we’ve seen an influx of homebrew RC controllers come our way, and we’re certainly not complaining. While the prices of commercial RC transmitters are at an all-time low, and many of them can even run an open source firmware, there’s still nothing quite like building …read more

ESP32 Adds Bluetooth to GameCube Controllers

While it might not be the most traditional design, there’s no debating that Nintendo created something truly special when they unleashed the GameCube controller on an unsuspecting world back in 2001. Hardcore fans are still using the controller to this day with current-generation Nintendo consoles, and there’s considerable interest in …read more

ESP32 Alarm Clock Doesn’t Skimp On The Features

The ESP family of microcontrollers is absolutely on fire right now, with a decent chunk of the projects that come our way now based on one of the impossibly cheap WiFi-enabled boards. In fact, they are so cheap and popular that we’ve started to see a somewhat unexpected trend; people …read more

Hacker Abroad: Visiting Espressif and Surprising Subway Ads

Thursday was my final day in Shanghai. After spending all of Wednesday at Electronica Asia, I headed over to the Espressif Headquarters which is just one subway stop away. This is of course the company behind the well-known ESP8266 and its younger sibling, the ESP32. My host was Ivan Grotkothov, …read more

RemoteDebug for ESP Platforms

Debugging tools are critical to quick and effective development. Without being able to peek under the hood at what’s really going on, it can be difficult to understand and solve problems. Those who live on the Arduino platform are probably well acquainted with using the serial port to debug, but …read more

Infinity Icosahedron Is Difficult To Contemplate Even Looking Right At It

Cubes and pyramids are wonderful primitive three-dimensional objects, but everyone knows that the real mystical power is in icosahedrons. Yes, the twenty-sided polyhedron does more than just ruin your saving throws in tabletop RPGs – it can also glow and look shiny in your loungeroom at home.

[janth]’s build relies on semitransparent acrylic mirrors for the infinity effect, lasercut into triangles to form the faces of the icosahedron. The frame is built out of 3D printed rails which slot on to the acrylic mirrors, and also hold the LED strips. [janth] chose high-density strips with 144 LEDs per meter for …read more

Hackaday Podcast Ep6 – Reversing iPod Screens, Hot Isotopes, We <3 Parts, and Biometric Toiletseats

What’s the buzz in the hackersphere this week? Hackaday Editors Elliot Williams and Mike Szczys recap their favorite hacks and articles from the past seven days. In Episode Six we cover an incredible reverse engineering effort Mike Harrison put in with iPod nano replacement screens. We dip our toes in the radioactive world of deep-space power sources, spend some time adoring parts and partsmakers, and take a very high-brow look at toilet-seat technology. In our quickfire hacks we discuss coherent sound (think of it as akin to laminar flow, but for audio), minimal IDEs for embedded, hand-tools for metalwork, and …read more
